I have a Montana on the way, and this thread has been a great resource. After years with a Zumo and Etrex combo, I’m looking forward to a do-it-all unit. But I have a question.

I have always created my road and dirt road routes in Mapsource using the routing tool. I place vias on lots of intersections, and set the unit to navigate by ‘shortest distance.’ This has worked everywhere I have been in the conti USA, including the CDR. Will this approach still work on the Montana, assuming I am using City Nav? I ask because there was a post suggesting that points on intersections cause trouble on the Montana. Is that correct?
